TO ALL WHOM ITy MAY CONOERN: Y

vBe it known that wefRurUs CAMPBELL and ALBION P. CAMPBELL, of Hillsdale, in the county of Hillsdale, and State of Michigan, have invented certain new and usefullmprovements in Brick-Machines; and we do hereby declare that the following isal full and complete des'c'ription'of Vthe same, reference being had to the accompanying drawings, making a part of this specification, in' which- I Figure is atop view of the machine.

Figure 2 is a side view;

Figure 3 is a rear end view.`

Like letters of reference refer to like parts in the several views. p

In. lig. 2, A is a frame, in the top of which is fitted an adjustable mould-bed', B, g. 1,`which forms the top of theV machine, and o n which the mould C is placed, in order to be pushed under the jack-mould D, as will hereinafter be shown. i

Fixed to the top of the frame is a supplementary frame, E, in which is fitted a Weight, F, which, together vwith the frame, constitutes the press.

Gr, fig. 3, is a beam, extending lengthwise across theweight.; is also a beam, and which is connected to the beam G .by means of the links I, whereby the two beams'and weight are operated conjointly, by means` of the lever J, to which it is connected at the point d, fig. 3, said lever'being attached to the lower side of the frame by a yoke, K.' v

L is a shaft, to the outer endof which is keyed a wheel, M, to the periphery of which is attached one end of a chain, N, iig. 2, whereas the opposite end is attached to 'the`beam H, by first being passed over the sheave d. A corresponding Wheel and chain are arranged on theopposite'sidelof the machine, as shown in iig. P is a lever, wherebysaid shaft is operated, as and for a purpose hereinafter shown.

Proceeding from the centre of thev shaft L is an arm, A', to the upper end ofwhich is lpivoted the bifur cated arms B', the outer ends of which areconnected to the slide C' by the intervention of the dependent arms D', and whereby said slide is Amoved backward'and forward on the wheels E.

F', lig. 1, is a shaft, journalled transversely across the front of theframe, immediately under the bed. On

said shaft are secured the cams, indicated by the dotted lines a,'g. 2, on the finger of which the bed rests,

whereby said bed may be raised upward and downward, for a purpose hereinafter shown.'

Having thus described the construction and'arrangement of the machne, t he practical operation of the same is as follows:

The rear end of the machine, as shown Ain' fig. 3; is placed close to the mud-mill, and in such a position as to bringthespace immediately above the jack-mould' in open relation to the mouth of said mill, so that the clay, as it passes from the mill, falls directly 4into the jack-mould, and upon which the weight is made to fall by treading upon the lever J, whichwill bring the weight down upon the clay, forcing it down through the-jackmould, into the mould immediately below.- lhis'being done, the mould and its contents aredpush'ed from under the jack Vto the front by placing another mould upon the bed, between it and the edge of the slide C'; then, on pushing thev lever P back in direction of the line a', fig. 2, will turn the shaft L, to which thc arms A' and B' are attached, the resultof which will be to draw the slide forward, thereby crowdingjhe mould C out from under the jack to the front part of the table or bed, from. which itis taken, the bricks removed, and the mould again laid upon the bed, to be pushed under the jack-mould for refilling, as before. 'lhus the empty mould is made to displace the filled one followingit, and at the same time pushing it from under. the jack mould, for the reception of the clay as .it may be forced down through the jack. i

i E" is a weight, attached to the slide by a cord or chain, b, passing over a sheave, the purpose of which is to assist in drawing buck the slide from the jack-mould to the position shown in iig. 2l.`

The lever G', g. 1,'secured to the shaft F', is for the purposcofworking the cams a, referred to', and on which the mould-bed rests, as above said. Thus, should a stone or other-'obstruction get into the jack, and

prevent the mould from being pushedo'nt, the bed `can be lowered by meansof the bams, and thereby allow the mould to pass freely out.

The rear end of the bed is adjusted by meansvof the slotted stays H', by loosening the nuts by which they n 'are secured to the machine. Also, by this means, ythe bed may be adjusted for making thin or thick bljic'ks.

We are aware that the ydevices herein described, taken' separately, are not new, but What we elaim, is- The wheels M, chain N, lever J, and beam H, constructed and arranged to operate in combination with the weight F, in the manner as and for the purpose set forth.

ALBION P. CAMPBELL.
